Energy Transfer: Heat, Light, Sound

Energy does not stay in one place — it moves. Heat warms a cold spoon left in soup, sunlight reaches us across millions of kilometers (about 0.62 miles per km) of empty space, and the sound of a friend\'s voice travels across the room to your ear. Each kind of energy travels in its own way.

1Describe how heat moves by conduction, convection, and radiation
2Identify everyday examples of heat, light, and sound transfer
3Compare how heat, light, and sound travel through different materials
